Portable computer control experiment system

Abstract

The invention provides a portable computer control experiment system, which belongs to the technical field of control experiments. A typical object control device for the system comprises a controlled device, a signal acquisition device for acquiring signals outputted by the controlled device and a load device for interfering the signals outputted by the controlled device. The typical object control device adopts a DC motor speed regulation device and a temperature heating control device, MATLAB/Simulink is adopted for modeling in a control system and simulation research on a control algorithm, a control code after simulation verification is directly used for being converted to an actual system control code, the software of an upper computer is written also by adopting MATLAB, and the whole development work is completed in the same working environment. The DC motor speed regulation device adopts a vertical motor base as a device for fixing the motor, the appearance is delicate but the mass is large, and jitter generated during the motor rotation process can be prevented. A copper block of the temperature heating control device is fixed in the middle position of a heating cushion, and uniform heating is ensured. a heating copper block adopts a vertical placement mode, and temperature control is facilitated.

Description

Technical field [0001] The invention belongs to the technical field of control experiments, and specifically relates to a portable computer control experiment system. Background technique [0002] In the study and research of automatic control theory, simulation and experiment occupy an important position. At present, there are mainly two types of automatic control principle experimental systems: one is an experimental system based on DCS or PLC, which has powerful functions, complete software and hardware resources, and flexible and rich control algorithm programming; the other is an experimental system based on single-chip microcomputers. This kind of experimental system is relatively cheap and easy to use. However, the above two kinds of experimental systems either have the disadvantages of expensive and bulky; or require developers to perform secondary programming, which leads to the modeling and control of the control object of this experimental system. In the aspect of alg...
